Ubuntu (

free and open source software. Ubuntu provides an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation. Ubuntu has been selected by readers of desktoplinux.com as the most popular Linux distribution for the desktop, claiming approximately 30% of Linux desktop installations in both 2006 and 2007.[5][6]

Ubuntu is composed of multiple software packages of which the vast majority is distributed under a

Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth. By keeping Ubuntu free and open source, Canonical is able to utilize the talents of community developers in Ubuntu's constituent components. Instead of selling Ubuntu for profit, Canonical creates revenue by selling technical support
and from creating several services tied to Ubuntu.

Canonical endorses and provides support for three additional Ubuntu-derived operating systems: Kubuntu, Edubuntu and Ubuntu Server Edition. There are several other derivative operating systems including local language and hardware-specific versions.[7]

Canonical releases new versions of Ubuntu every six months and supports Ubuntu for eighteen months by providing security fixes, patches to critical bugs and minor updates to programs. LTS (Long Term Support) versions, which are released every two years,

Karmic Koala
), was released on October 29, 2009.

History and development process

Ubuntu is a fork of the Debian project's code base.[10] The original aim was to release a new version of Ubuntu every six months, resulting in a more frequently updated system. Ubuntu's first release was on October 20, 2004.[11]

Ubuntu is released a month after

hardware drivers.[13]

Ubuntu packages are based on packages from Debian's

Debian Sarge
to remain compatible.
[16] Before release, packages are imported from
frozen
, and packagers then work to ensure that the frozen features interoperate well together.

Ubuntu is currently funded by

Ubuntu Foundation and provided an initial funding of US$10 million. The purpose of the foundation is to ensure the support and development for all future versions of Ubuntu. Mark Shuttleworth describes the foundation as an "emergency fund" (in case Canonical's involvement ends).[17]

Ubuntu 8.04, released on April 24, 2008, is the current Long Term Support (LTS) release. Canonical releases LTS versions every two years, with Ubuntu 10.04 Lucid Lynx (release number subject to change) scheduled as the next LTS version in 2010.[18][19][20] The current regular release, Ubuntu 9.10 (Karmic Koala), was released on October 29, 2009.

On March 12, 2009, Ubuntu announced developer support for 3rd party

Amazon EC2.[21]

Ubuntu focuses on

PolicyKit is also being widely implemented into the desktop to further harden the system through the principle of least privilege
.

Ubuntu comes installed with a wide range of software that includes

Shields Up test; Ubuntu recommends installing Firestarter and testing it using Shields Up.[25]) GNOME (the current default desktop) offers support for more than 46 languages.[26] Ubuntu can also run many programs designed for Microsoft Windows (such as Microsoft Office), through Wine or using a Virtual Machine (such as VMware Workstation or VirtualBox
).

Installation

Ubuntu 9.04 (live CD session)

Installation of Ubuntu is generally performed with the

RAM
.

Users can download a disk image (.iso) of the CD, which can then either be written to a physical medium (CD. DVD), or optionally run directly from a hard drive (via UNetbootin). Ubuntu is even available on the PowerPC platform (enabling users of older Macintosh computers to run Ubuntu natively on their machines); however, it is no longer officially supported.

Canonical offers Ubuntu[28] and Kubuntu[29] installation CDs at no cost, including paid postage for destinations in most countries around the world (via a service called ShipIt).

hard drive
. Wubi also makes use of the Migration Assistant to import users' settings. It is only useful for Windows users; it is not meant for permanent Ubuntu installations and it also incurs a slight performance loss.

Remastering

Various programs (such as remastersys and Reconstructor) exist to produce customised remasters of the Ubuntu Live CD.

Package classification and support

Ubuntu divides all software into four domains to reflect differences in licensing and the degree of support available.

Canonical Ltd.
.

free software non-free software
supported Main Restricted
unsupported Universe Multiverse

Free software includes only software that has met the Ubuntu licensing requirements,[36] which roughly correspond to the Debian Free Software Guidelines. Exceptions, however, include firmware and fonts, in the Main category, because although they are not allowed to be modified, their distribution is otherwise unencumbered.[37]

Non-free software is usually unsupported (Multiverse), but some exceptions (Restricted) are made for important non-free software. Supported non-free software includes device drivers that can be used to run Ubuntu on some current hardware, such as binary-only graphics card drivers. The level of support in the Restricted category is more limited than that of Main, because the developers may not have access to the source code. It is intended that Main and Restricted should contain all software needed for a general-use Linux system. Alternative programs for the same tasks and programs for specialized applications are placed in the Universe and Multiverse categories.

In addition to the above, in which the software does not receive

backport newer software from later versions of Ubuntu.[38]
The repository is not comprehensive; it consists primarily of user-requested packages, which are approved if they meet quality guidelines. Backports receives no support at all from Canonical, and is entirely community-maintained.

The -updates repository provides updates to stable releases of Ubuntu and are generally installed through update-manager. Each release is given its own -updates repository (e.g. intrepid-updates). The repository is supported by

Canonical Ltd. for packages in main and restricted, and by the community for packages in universe and multiverse. All updates to the repository must meet certain requirements and go through the -proposed repository before being made available to the public.[39]
Updates will continue to be available until the end of life for the release.

In addition to the -updates repository, the unstable -proposed repository contains uploads which must be confirmed before being copied into -updates. All updates must go through this process to ensure that the patch does truly fix the bug and there is no risk of regression.[40] Updates in -proposed are confirmed by either Canonical or members of the community.

Availability of third-party software

Ubuntu has a certification system for third party software.

Adobe's Flash Player plugin, many common audio/video codecs, and unrar, an unarchiver for files compressed in the RAR file format
.

Additionally, several third party application suites are available for purchase through the Canonical web-based store, including software for DVD playback and media codecs.

There are two Ubuntu releases per year, using the year and month of the release as the version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on October 20, 2004.[47] Version numbers for future versions are provisional; if the release is delayed the version number changes accordingly.

Ubuntu releases are also given code names, using an adjective and an animal with the same first letter (e.g., "Dapper Drake" and "Intrepid Ibex"). With the exception of the first three releases, code names are in alphabetical order, allowing a quick determination of which release is newer. Commonly, Ubuntu releases are referred to using only the adjective portion of the code name.[48]

Releases are timed to be approximately one month after GNOME releases (which in turn are about one month after releases of

8.04 Hardy Heron) have been labeled as Long Term Support (LTS) versions, to indicate that they will be supported (with updates) for three years on the desktop and five years on the server,[49] compared to the 18-month support period for non-LTS releases.[50]

The current release is

9.10 Karmic Koala,[51] released on October 29, 2009. Some users have reported hardware-recognition and functionality issues on upgrading to this version from previous versions of Ubuntu.[52]

Variants

Kubuntu is an official variant of the Ubuntu distribution which uses KDE rather than GNOME

Several official and unofficial Ubuntu variants exist. These Ubuntu variants install a set of packages that differ from the original Ubuntu distribution.

Official variants store packages and updates in the same repositories as Ubuntu, so that the same software is available for each of them and is generally compatible between the official variants. The Ubuntu derivatives that are fully supported by Canonical are[7]

The following are Canonical-sponsored derivatives:

There are also many

Canonical Ltd., which are generally fork
customizations that have been created for specific goals.

System requirements

The desktop version of Ubuntu currently supports the

ARM[59] architectures. Some server releases also support the SPARC architecture[60][61] Unofficial support is available for the PowerPC,[62] IA-64 (Itanium) and PlayStation 3
architectures.

Development

UDS Karmic Group Photo

The Ubuntu Developer Summit is a gathering of software developers which occurs prior to the release of a new public version of Ubuntu.

At the beginning of a new development cycle, Ubuntu developers from around the world gather to help shape and scope the next release of Ubuntu. The summit is open to the public, but it is not a conference, exhibition or other audience-oriented event. Rather, it is an opportunity for Ubuntu developers, who usually collaborate online, to work together in person on specific tasks.

Reception

In an August 2007 survey of 38,500 visitors on DesktopLinux.com, Ubuntu was the most popular distribution with 30.3% of respondents claiming to use it.[6]

In January 2009 the

ZDNet reported "Worldwide, there are 13 million active Ubuntu users with use growing faster than any other distribution."[65][66]

Ubuntu was awarded the Reader Award for best Linux distribution at the 2005 LinuxWorld Conference and Expo in London,[67] has been favorably reviewed in online and print publications,[68][69][70] and has won InfoWorld's 2007 Bossie Award for Best Open Source Client OS.[71]

Mythbusters, has advocated Linux, specifically giving the example of Ubuntu, as an alternative to proprietary software, citing software bloat as a major hurdle in proprietary operating systems.[72][73]

Ubuntu has also received negative assessments. In early 2008

PC World criticized the lack of an integrated desktop effects manager, although this did not prevent them from naming Ubuntu the "best all-around Linux distribution available today".[74]

The Ministry of Education and Science of

Macedonia deployed more than 180,000 Ubuntu Linux based classroom desktops, and has encouraged every student in the country to use Ubuntu-powered computer workstations.[75]

The French police is in the process of installing Ubuntu on 90,000 workstations, demonstrating a 70 % saving on the IT budget without having to reduce its capabilities [76].

Vendor support

A number of vendors offer computers with Ubuntu pre-installed, including

Fingerprint Readers, HDMI, Bluetooth, DVD Playback (using LinDVD), and MP3/WMA/WMV.[82]
